Specifically, in this embodiment, the power supply voltage connection end n 1 of the battery rod 11 is connected to the ground voltage connection end m 2 of the vaporizer 12 , and the ground voltage connection end n 2 of the battery rod 11 is connected to the power supply voltage connection end m 1 of the vaporizer 12 . Specifically, the power supply voltage connection end n 1 of the battery rod 11 is connected to the power supply voltage output end VCC, and the ground voltage connection end n 2 of the battery rod 11 is connected to the ground voltage output end GND.
  • the vaporizer 12 is inserted into the battery rod 11 , and the battery rod 11 supplies power to the vaporizer 12 and sends data to the vaporizer 12 .
  • the vaporizer 12 feeds back identification information to the battery rod 11 , for the battery rod 11 to use, according to the identification information, a corresponding power to drive the vaporizer 12 , to avoid the mixing of the battery rod 11 and the vaporizer 12 .
  • a difference in driving powers causes the odor of smoke or the amount of smoke to be too small or too large.
  • a difference in resistance values of the heating wire leads to cases such as overcurrent protection and no smoke generation.
  • the battery rod 11 and the vaporizer 12 can be identified with each other, and the battery rod 11 can use the power matching the vaporizer 12 to drive the vaporizer 12 , thereby improving the user experience.
  • the electronic vaporization device described in this embodiment enables the vaporizer 12 to be inserted into the battery rod 11 rightly or reversely, and the vaporizer 12 can be inserted into the battery rod 11 rightly or reversely without affecting the communication between the battery rod 11 and the vaporizer 12 .
  • the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise.
  • the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
